Young’s modulus of elasticity Y is expressed in terms of three derived quantities, namely, the gravitational constant G, Planck’s constant h and the speed of light c, as Y = cαhβGγ. Which of the following is the correct option?
(A) α = 7, β = –1, γ = –2
(B) α = –7, β = –1, γ = –2
(C) α = 7, β = –1, γ = 2
(D) α = –7, β = 1, γ = –2
